我创建了一个自定义的CursorAdapter并希望选择一个列表项,以便在onOptionsItemSelected中启动一个动作。用于CursorAdapter的onClick监听器
创建列表视图:
public void onCreate(Bundle savedInstanceState) {
Log.d(TAG, "onCreate called");
super.onCreate(savedInstanceState);
Log.d(TAG, "create DatabaseOpenHelper");
DatabaseOpenHandler helper = new DatabaseOpenHandler(this);
Log.d(TAG, "get writeable database access");
database = helper.getWritableDatabase();
Log.d(TAG, "create Cursor for database access");
Cursor data = database.query(DatabaseConstants.TABLE_NOTES, fields,
null, null, null, null, null);
Log.d(TAG, "set NoteCursorAdapeter");
setListAdapter(new NoteCursorAdapter(this, data));
}
onOptionItemSelected:
public boolean onOptionsItemSelected(MenuItem item) {
Log.d(TAG, "onOptionItemSelected called");
switch (item.getItemId()) {
case R.id.conference_note_menu_new:
Toast.makeText(this, "Es sind keine Einstellungen verfügbar",
Toast.LENGTH_LONG).show();
return true;
case R.id.conference_note_menu_edit:
Toast.makeText(this, "Es sind keine Einstellungen verfügbar",
Toast.LENGTH_LONG).show();
return true;
case R.id.conference_note_menu_delete:
Toast.makeText(this, "Es sind keine Einstellungen verfügbar",
Toast.LENGTH_LONG).show();
return true;
default:
return super.onOptionsItemSelected(item);
}
}
不能在互联网上找到任何有用的信息。
